Laser fork light barriers
F-LAS Series
The laser light barriers of F-LAS series allow the solution of complex problems (curve discussion, tolerance band monitoring, etc.).
Functional principle:
The signal at the analog output decreases proportionally with increasing laser beam covering.
Collimated laser beam:
The laser light beam that is emitted by a high-precision optical unit allows the very precise detection of smallest objects (e.g. threads) even in case of a large transmitter/receiver distance. The low divergence of the light beam almost completely reduces the measuring error that is caused by moving the measuring object from the transmitter in the direction of the receiver.
Homogeneous light distribution:
The use of high-precision apertures in the transmitter ensures optimum adaptation to the respective application. Apart from a large variety of standard apertures special apertures can be realised. The aperture ensures an homogeneous light distribution in the beam and a sharp beam limitation.
Monitor signal:
In addition to the switching signal the fork light barriers of series F-LAS also provide an analog signal. "Monitoring" of the analog voltage allows a better evaluation of the switching signal. The output can also be used for measuring tasks.
These sensors mainly are characterised by their high switching frequency (typ. 25 kHz in case of line F-LAS-DC, and typ. 200 kHz in case of line F-LAS-DC-HS), the large variety of fork sizes and apertures, and their high switching accuracy.
